PROBLEM TO BE SOLVED: To provide an expanded polyurethane foam that has an excellent fire retardance and a good slipperiness and is used for a composite skin material in use for a vehicle or the like. SOLUTION: The expanded polyurethane foam has a mean coefficient of friction (MIU) of 10-20 and a mean deviation of mean coefficient of friction (MMD) of 0-5 , when the pressure to the surface of the contact probe in KES (Kawabata evaluation system) measurement is 9.8 kPa/m<SP>2</SP>. The laminated sheet material comprises laminating a fibrous sheet or a leather sheet to at least one side of the expanded polyurethane foam. COPYRIGHT: (C)2004,JPO |
